Glass bangles are mostly produced in only one Indian city called Firozabad in North India. Bangles that were made from plastic started replacing the glass bangles. Glass bangles are usually smooth, with some texture or set with stones.
However, in many cultures, especially in the Arabian Peninsula and in South Asia, bangles have evolved into various types in which different ones are used at different occasions. In India, Hyderabad has a historic market for bangles named the Laad Bazaar. In Pakistan, glass bangles are almost all produced in Hyderabad, Pakistan. Glass bangles are found in many colors.
Diamonds are forever
You may be familiar with the term, 'Diamonds are Forever'. It is made popular by the De Beers advertising campaigns and for good reason. They have been used throughout the ages as bearers of mystic powers and incredible beauty. Not only are these diamonds rare in numbers but also in the number of skilled artisans that can complement their exquisite beauty.
Part of the credit for the almost mythical reverence to diamonds throughout the years belongs to the fact that these beauties are quite rare in their most sought after gemstone quality form. Through the centuries they have been revered and admired by many civilizations. When it comes to history, diamonds have a very long and fascinating record as one of the most intriguing gemstones on the planet. Forged billions of years ago, long before dinosaurs roamed the planet, they have survived the forces of nature to reach us.
Gemstones are so durable
A few are mineraloids not true minerals and are including here: opal, amber, and moldavite. Foremost is durability - it must not easily corrode away, nor can it be brittle. It is so durable that nearly all of the gold ever mined is still in circulation or storage. In some cases, the names are true misnomers, such as Green Amethyst for prasiolite-a transparent green variety of quartz.
In most cases, these variety names are historical, as the gemstones were not recognized as being varieties of other minerals until well after the name was in common use such as aquamarine, emerald, and heliodor as varieties of beryl. And that is related to the third characteristic, ductility. You can see the options are endless and when you are commissioning a piece, why compromise a thing when you can choose!
